Hello all,

I just replaced the engine temp sensor cause I noticed the primary fan didn't come on at 228 degrees like it normally does. Once the temp reached 231, I turned on the AC so primary and secondary fans would run....and they did cooling it down. Anyway after sensor replaced the primary come on again at 228 degrees. The Service manual say 226 it should come on and down to 217 before it shuts off. A little confusing in the manual cause it says the primary should come on at 219? Maybe I'm reading it wrong, maybe somebody can add here. Both fans work with the AC on. 1993....thanks!
